It .is an object" of this inventionto' improve "the presentd'ay splitterrroll rapparatus andto pro- .vide simple, practical and *durable "apparatus "or this kind.

Another tobjectcof the invention .-is ito :provide rarsplitter roll'assembly WhiChrlS readily 1 transferab-le and i movable .as: a unit.

.Another object -.of the invention :is :to ,tprovide iapparatus whereby i a splitter roll may be readiily mounted and I demounted, :and wherein rposiitive means are provided: for driving: a splitter roll at a predetermined rate of speed.

Another object of the invention is to provide a .plurality' of splitter'rolls which may be driven in unison at uniform speed which is not necessarily the same surface speed "as thespeed of travel of the zwarp she'et.

Other objects of the invention will bein part obvious or in part pointed out hereinafter.

.Theinvention accordingly .consists inzthefeatures rdr "construction, combinations of *elements, farran gementsof parts, and'in'the severalisteps and relation and order of each .of said --steps .to one orimorelofthe others thereof, all as willbe pointed out in'the "following descriptioni and the 'scope'ofthe application or which will be indicated in the following-claims.

The-invention will best be "understood ift'he following .description is read in connection with the drawings, in which:

Figure l is a front elevational view of a splitter roll assembly including mounting means and drive means;

Figure 2 is an end view looking in the direction of the arrow shown at the right in Figure 1;

Figure 3 is a vertical sectional view taken on the line 33 of Figure 2; and

Figure 4 is a detailed view showing one end of one of the splitter roll spindles.

In the preferred form of the invention disclose'd therein I provide the :brackets 10 :and 2H :proje'cting iforwardly .ZfrOm :-fsupport members it sand lrtzandishownherein asbeing attached thereto by screws s.

A. singlei 'spindle'm'ember. 25 is mounted to extend throughthealigned-aper- :ture". 3 .of' the armsaofieachcof'the brackets i0. and -12 irespectively, and-. tworspin'dles -126 .are shown -mounted one abovezthe other: .inthe alignedfapertures 2b of the arms of each :braclret. Each'spin- -d-le projects through blocks ZJLPIOVidSd on the :inside and the "outside of each "arm of said brackets 10 and i2 respectively, each block being slotted longitudinally and held against the .,braci:et arm by means i of i nut-boltccombinations ctheiblocks for mounting.the-spindlein aper- -.tures i8 being mounted {on ibolts 'iexten'din'g t'hrough slot :22, and'theblocks for=n1ounting the "two spindles inzaperturei-zfi rbeingunounted 'on 'bolts-extending through-slot. 2 L ifiplitter'. rods :56 are mounted between aligned ispindiescarried by the .opposed'brackets as has ibeendescribed. Thus one splitter. rod is mounted between 'the spin'dies iin apertures 18, and ttwo pairs of splitter rods 33!! are 1 provided within the apertures -:2.-i: .in-the 5 arms :of :-braol:ets it and .i 2 respectively. As shown herein the zsplitterfrods 1:3 [bare readily interchangeable-as are'thespindles 126. .At. least one end, and:asvshown-hereinpref- .erably both ends'of a*s plitter:bar are tapered and flattened and --adapted ito *be :received .in a V- shapedaperture s26 providedat the inner: end .of each of the spindle :members 26. iAlso mounted on each spindle member is a collar 28 which is 'slideable forwardly against the shoulder 26 to prevent accidental displacement and disengagement of an end of a splitter roll from a spindle aperture 26, and a spring clip 26 may be provided to retain the collar 26 in position.

The spindles 25 are mounted in ball bearings 36 carried by the blocks b and each spindle is thus freely rotatable. On one end of each spindle, beyond the mounting bracket, a sprocket S is provided by which power from any suitable source may be transmitted to the spindle as for example by a chain 38, see Figure 2, which as shown herein passes over the sprockets S on the spindle ends outside of bracket l2, and over the idler 40, and is positively driven from sprocket 42 on jack shaft 44 which in turn is positively rotated by the chain 46 from any suitable source of power. Thus the speed of rotation which may be imparted to the splitter rods is entirely independent of the speed of travel of the warp sheet 4 non-circular in cross section, and the said rotatable bearing of each pair having a recess of noncircular cross section to receive the said noncircular end of said rods, adjustable mounting means for one or more of said pairs of bearings whereby the distance between said pairs of bearings respectively is adjustable, and means for rotating the said rotatable bearings in timed which may be divided first by the single rotating splitter rod positioned between the brackets l0 and 12 adjacent their free ends, and each resulting sheet being split again by one of the rotating splitter rods mounted between the brackets Illand I2 adjacent their ends attached to support members M and 16 respectively.

The apparatus described herein has the advantage of being readily assembled to a drying box, such for example as the kind disclosed in copending application of Paul R. Rose, Serial No. 25,565, filed May '7, 1948, Patent No. 2,541,383, now Reissue No. 23,535, and is readily transferable as a unit to another drying box.

It will thus be seen that there has been provided by this invention an apparatu in which the various objects hereinabove set forth together with many thoroughly practical advantages are successfully achieved.- As various possible embodiments might be made of the mechanical feaplurality of sheets comprising a rod, rotatable spindles for receiving the ends of said rod, and means for rotating said spindles one of said spindles having a slot extending across its face diametrically to permit insertion of a rod end through the side of the spindle, and means forlocking said rod end in said spindle.
